our outback 295RE is three years old. Have traveled almost 15K miles with it. Have camped in it close to 90 days/year (270 days total), about 1/2 have been dry camping, 1/4 in state parks, 1/4 in RV parks.
Warranty issues: ONE, clear coat on aluminum wheels showed small pits at 1 year, Resolution: Keystone replaced all 4 wheels with new wheels, paid for mounting and balancing the tires.
Wear and tear: Everything is still in excellent shape, even after many trips with grandkids.
so, yes we are very happy with ours, Love the floorplan and and layout. IMHO it is a mid range trailer, perfect for our use. No it doesn't have corian counters, etc. but we don't care.
One downside is it really is only a three season trailer, regardless of "artic pack" claims. We've found it fine as long as daytime temps are above freezing and nights don't get below about 20F. Anything colder, and I suspect it would be marginal. Same for high temps, above about 90F only one 13.5K BTU AC is marginal, although newer ones have a 15K option.
Would we buy another one? In a heartbeat, assuming there is a floorplan we liked.
